As they exist in nature, elements usually have no charge.
However, there are certain tendencies of elements to become anions (ions with negative charges) or cations (ions with positive charges) based upon their individual compositions.
Imagine the Periodic Table and it's groups. The transition metals in the middle of the table form various cations that are not easy to predict. Therefore, we can't represent all transition metals as their own group with one specific charge. But, we CAN do that for some other groups:
Group 1 elements (Li, Na, K etc.) have similar chemical properties that make them "want" to have a charge of +1.
Group 2 elements form 2+ ions, and
Group 3 elements form 3+ ions.
Group 4 elements may have a charge of either 4+ or 4- and need to be memorized.
The elements that form negative ions are in Group 6 (2- charge) and Group 7 (1- charge).
Noble gases have their outermost energy levels full of electrons and are "balanced" and thus have a very low tendency to become ions.
In order to reasonably assume the charge of an element in an equation, you have to consider the other elements it will be reacting with and take into consideration their properties as well.
For example, when Hydrogen and Oxygen combine to form water, two Hydrogen atoms bond with one Oxygen atom. Say you remember that Oxygen is in Group 6 on the periodic table and Group 6 elements have a 2- charge. Say you also remember that Hydrogen is a noble gas without a charge listed. Since the Oxygen atom has a 2- charge, each Hydrogen atom will have to have a +1 charge to attract to the oxygen and bond with it (this is because molecules like to be neutral and form a net charge of zero).

∙ 13y agoAn atom of an element will have a neutral charge, or no charge. When the atom loses or gains one or more electrons, however, it will have a charge and is referred to as an ion. In general, an ion is not found running around free of any other element - it will be associated with another ion formed from a different element and therefore would be a compound.

What is the Significance of the periodic table of elements?
Periodic table is a tool to study elements. Their properties can be studied easily.
The periodic table is based on an element's what?
The periodic table is based on an element's number of atoms. The elements are arranged from least to most number of atoms.
Does an atoms nucleus have a positive or negative charge?
it cant have any charge at all. atoms have an equal amount of protons and neutron therefore the give off no charge. if they did give off a charge they would no longer be atoms they would be ions
Which atoms will always be radioactive?
Almost all the lower elements in the periodic table will always be radioactive.
What are the bad parts of a food atom?
There is no such thing as a food atom, all atoms are listed on the "Periodic Table of Elements".
What are some exmple on the periodic table that are neutral atoms?
All the atoms are neutral. Only ions have an electrical charge.
Do Atoms have no overall eletric charge?
Elements, as they appear on the Periodic Table, have no net charge. They all have equal numbers of protons (+) and electrons (-). HOWEVER, an atom can gain or lose electrons, which will change its charge, but, again, on the periodic table, they all have 0 charge.
What are atoms and elements on the periodic table?
The periodic table contain all chemical elements. For the table see the link below.
Where do radioactive atoms start on the periodic table?
After lead, all elements on the periodic table have only radioactive isotopes.
What can you find in nature that relates to the periodic table?
Everything. The periodic table relates all of the smallest particles of nature into a table showing all of these smallest particles (atoms).
What is the Significance of the periodic table of elements?
Periodic table is a tool to study elements. Their properties can be studied easily.
Is there any Atom not on the periodic table?
This question does not make sence. The periodic table is a chart of all of the elements know to man. All of these elements are composed of atoms (as is all matter).
The periodic table is based on an element's what?
The periodic table is based on an element's number of atoms. The elements are arranged from least to most number of atoms.
Does an atoms nucleus have a positive or negative charge?
it cant have any charge at all. atoms have an equal amount of protons and neutron therefore the give off no charge. if they did give off a charge they would no longer be atoms they would be ions
Do all elements of the periodic table have the same type of atoms?
No. Atoms differ in number of protons, neutrons and electrons.
Do all atoms on the periodic table wish they were gold?
No. The elements does not have minds like humans.
What do all atoms of the same elemnt have?
All atoms of the same element have the same number of protons in their atomic nuclei. The number of protons is the atomic number for that element on the periodic table. The elements are arranged in order of increasing atomic number on the periodic table.
